Application filed January 13, Serial 1T0. 529,528.

Toall whoin it may cbn'cem- E v 5 Be it known that I, JOHN F. D NIKE acitizen of the United States, residing at Adonis, in the county of Polkand Statev of Missouri, have inventednew anduseful Improvementsinvalve-springTools, of which the following is a specification.v

'Z'his invention. relatesto tools especially des gned for use n.removmgwalves. from internal combustion-engines andihas for an objectthe provision of, a tool by means of which .the valve spring maybecompressed to facilitate, thefremoval of thevalve.

Another object of the ,invention; is. provisionof a tool as above setforth,- which is adjustable to permit ofitsuse with valves 1 ofdifferent lengths and upon. engines where the invention further.includes thefollow ling. novel features and. details of construction, tobe hereinaftermorefully;described,

illustrated in V the accompanying: .1 drawings and pointed out in theappended claims.

In the drawings I Figure 1 is asideeleyation of a tool constructed inaccordance with the invention and illustrating its application Wheninuse.

Figure 2 is a top plan view of the same.

Figure 3 is an edge View.

Figure 1 is a section on the line 4 4: of Figure 1.

Figure 5 is a view similar to Figure 1 but showing the position of theparts when the valve spring is compressed. 7

Referring to the drawin'gs in detail, wherein like characters ofreference denote corresponding parts, the tool which comprises thesubject matter of'the present application includes a frame having rightangularly disposed members 10 and 11, the' said frame further includingan angle piece 12 to which is secured upon opposite sides, plates 13,the latter forming the member 10. The member 12 is of sectionalformation one of the said sections being formed by the formed tl eanglepiece 12, the said bolt the plates 14;, the; thumb nut 16 serving tohold thesections iii-adjusted position,

; Piyot'a -lly mounted 'u-pionla bolt 19 between replaces.n w a m 2 t ida mbeslot-.517 sis-Ve a. in: the act-16a which-is iconneoting thespacedplates 14:. Theother bolt 15 is carried by the member 12 ajnd ex tendsthrough :a slot 18 provided in each of Iii l'g provided with fspacedopenings 21 Wherelend fof thisarm is bifurcated as shown at ,i2 2 forthe reception of .the. ste1n.23, of ,a valve 24. T u l pri g 5-surrounds the stem 23.

Carried bygthe member 10 of the. frame and positioned between the plates13 of this member is a valve engaging element 32. This element isadapted for engagement with the valve 24. and is mounted between theplates 13 upon a bolt 33, which bolt. is V removably received withinopenings 34 so as to adjustably positionthe element 32."

In the use of the invention the .tool is positioned as illustrated inFigure 1. Adownward movement of the outer end of the oper-- ating lever27 will move the inner end of the arm 20 upward so as to compress thesame i i as illustratedin Figure 5 ofth'e drawings,

whereupon the valve may be readily removed.

By adjusting the sections of the'mem- 7 her 11 of the frame, thetool'may be adjust-. ed to valves of different 1engths,'while it may bealso adapted for use with different,

types of engines where the-position of the I valves within the cylinderblock may vary. The tool is adjusted to the length of the valve throughthe adjustment of-the member 11, while the element 32 may be movedlongitudinally of the member 10 of the 7 frame to properly position thesaid element for engagement with the valve.

For the purpose of holding the valve springs in compressed position,thereis mounted upon the pivot pin 28, a dog 35, which is adapted forengagement with a series of spaced notches 36 provided in the member'12, Pivot-ally mounted upon the operating lever 27, as shown at 37 isan arm 38 which is connected to the dog 35 by a link 39. A springllconnecting the arm 38 and the lever 37 serves to normallyforce the dog35 into engagement with the notches in the member 12. I

"When the valve spring has been compressed by the use of the tool, thedog 35 will engage one of the notches 36 and hold the spring incompressed positionuntil said dog is released by operating the pivotedarm 38.

The invention is susceptible of various changes in its form, proportionsand minor details of constructionand the right is herein reserved tomake such changes as properly fall within the scope of the append edclaims.

Having described the invention what is claimed is: V V

1. A valve spring tool comprisinga frame including right angularlyarranged members, a valve engagingelement carried by one of saidmembers,,a spring engaging arm pivotally mounted upon the other member,an operating lever pivotally securedto the frame and a link connectingthe arm and lever. I

2., A valve spring tool comprising a frame including right ,angularlyarranged member's, a valve engaging element carried by one of saidmembers, a spring engaging arm pivotally mounted upon the-other member,

the frame and engageable with said arm'and a link connecting thesupplemental lever with the operating lever.

" 3. A valve spring tool comprising a frame including right angularlyarranged members, one of said members being of sectional formation andincluding'a pairof spaced plates, meansfor adjustably connecting thespaced plates to the other section of said .4 an. operating leverpiv'otally secured to the 1 frame, a link connecting-the arm andlever, asupplemental clever pivotally secured to member, an ,armpivotally andadjustably mounted between the spaced plates, means located at one endof said arm for receiving the valve stem, whereby the arm may engage thevalve spring, an operating lever pivotally secured to the'sectionalmemberof the frame, a link connecting the arm andoperating lever andmeans adjustably secured to.

one of'said members, a spring engaging arm" pivotally mounted upon theothermember, an operating lever pivotally secured to the frame, a linkconnectingthe-arm and lever and a latch carried by the operating arm.and

engageable withthe frame for holding the tool in adjusted position.
